My parents have a will.
I am an heir.
I will inherit a portion of their earthly riches. A portion of their accumulated wealth and possessions are intended to go to me upon their death.
However, I am also a joint heir to the kingdom of Heaven.
Heavenly riches are mine because our "testator" Jesus did die thereby making me a joint heir with Him... and with you.
(See Hebrews 9:17 For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth.)
God is the King of kings and the Lord of lords.
We aren't simply inheritors of a token or bauble.
We are royalty!
Why then do we live as spiritual paupers? It ought not to be this way.
Let us be like the prodigal son who received the robe, the ring, the refreshment and the reunion.
Let us resist being like the other son who has access to all of it yet harbored bitterness and resentment in his heart.
God has granted us access to all He has through the death and resurrection of His Son.
Let's not squander it on pursuits of the flesh. Let us spend our inheritance sharing the truth and knowledge of our riches with our brothers and sisters that do not yet know they are fellow heirs too.
